Tiree's weather is dictated by the surrounding sea and the warming effects
of the Gulf Stream. The winter average temperature is a mild 5C while the
summer average is a modest 14C. Annual rainfall is about 1.15m / 45 inches.
April to June is the driest period when there is about half the monthly rainfall
of wetter September to January. Tiree is renowned as one of the sunniest
places in the United Kingdom. Also, the sun sets at about 22:22 on midsummer's
day, which is a whole hour later than London and 20 minutes later than Edinburgh.
Long summer days and great sunsets! As a flat exposed island, Tiree is inevitably
windy which has resulted in its almost treeless landscape.
